i have a 97 honda civic lx sedan 5 speed with a d16y8 auto swap, i changed the manifold to a manual one and it started throwing code p1509, i changed the intake manifold gasket, plugs, wires, cap, rotor, coil, 2 different idle control valves, 2 maps, 2 fit valves, repined the ecu, converted 3 wire to 2 wire, shit still throwing p1509 im running the auto harness but it should still be the same just a few extra wires, im running a manual p2p, any help would be greatly appreciated
